I think that's how Packard made them in the first place. At least they both have 3 1/2 inch bore, only the stroke is different.

Now that this question is to the top of the list (bump) maybe the real experts will chime in.

If not, you could measure the main bearing size and the length of the crank and if it measures up, try it in the block. If it fits and doesn't hit anything you should be in business.

On other engines with interchangeable crankshafts, it is important to use the rods that match the crank as they are different lengths. So I would use the rods as well.
